search about for food的意思|示意

In prehistoric times a group of about 60 people had many kilometers of empty land to wander and search for food in.

在史前时代，60人左右的群体会有数公里的空间来活动觅食。

In the evening, the digging for bodies ceases, as does the search for drinking water and food, for news about missing parents and friends.

晚上，挖掘被困人员及尸体的工作停下了，搜寻饮用水、食物、失踪父母及朋友讯息的工作也停下了。

Think about this: Five birds are resting on the fence and minutes later, three birds decide to fly off to search for food.

请思考这个问题：五只鸟在篱笆上休息，几分种后，三只决定飞走去寻找食物。
